In reality, an intel 520 SSD will be something that gives you a bit more performance by like 5 percent. Indelinx controller have not had enough time to mature. I would say that by the time we see a vertex 5, it might be a better drive than a sandforce one.

If you want sheer performance and have the cash, then check out OCZ revo drives.

The vertex 3 in raid 0 will not allow you to use it in sata 3. I had to use the sata 2 ports before it would work..

OHHHHHHHHHHHHHHHHHHHHH I think I see what you are trying to get at. Right now you have a raid 0 array with basically 550 mb/ps of read speed due to the use of the sata 2 ports. You are asking if the controller on the vertex 4 will be better suited for your marvell controlled sata 3 ports to see if you get better real world performance.

In which case the answe is I do not know. The indelinx stuff is too new and unexplored to be able to answer that. A good way arounf it though is to go with a revo drive. Since you would be using PCI instead of sata, you won't have controller issues.
